Apple's healthcare prospects intrigue industry observers

There's little doubt that Apple is planning to introduce some type of health and fitness solution, whether a device, software, a platform or all three. The question is the scale of the impact such a solution—coming from a company that's proven it can change the behaviors and expectations of people around the world—might have. For nearly a year, at least, there have been reports of Apple hiring professionals from fascinating areas of medicine—including Nancy Dougherty, who developed a tiny bandage capable of monitoring heart rate, temperature and other things; Michael O'Reilly, an anesthesiologist who's developed noninvasive patient-monitoring technologies; and Ravi Narasimhan, a specialist in machine learning and biomedical algorithms, among other things.
